ROTARY BRUSH.

Be it known that I, SIDNEY Ilm, a citizen of the United States of America, and a resident of New York, in the county and State of New York, have invented a certain new and useful Rotary Brush, of which the following is a'specication, the same being.l a full, clear, and eXact descrlption of .the 1nvention, such as will enable others skilled 1n the art to which it appertains to make and use the same. 1

This invention relates to instruments comprising a quantity of some flexible material attached to a handle or stock adapted for cleaning or rubbing purposes, and 1t appertains particularly to a portable appliance designed primarily to brush the filaments or capillary covering of the head by a rotatory movement.

My appliance may be used for the purpose of brushing away t e part1cles of halr resting on the shoulders of a persomwhose halr has been cut by a barber, or as an apparatus for a dry shampoo. Keeping in view these and other objects for which the appllance 1s adapted, the invention conslsts 1n the construction, arrangement and operatlon of parts hereinafter set forth. j

In the drawings whlch accompany and form a part of this specification and 1n which one example or application of the 1nvention is illustrated, Figure 1 represents" a side elevation of an apparatus constructed according to my invention; Figure 2 1s a side elevation, partly in section, of the brush shown in Figure 1; Figure 3 is a side elevation, partly in section, of an appliance wherein the actuating means forms a partv of the same; Figures 4 and 5 are views o f the devices illust-rated in Figures 2 and 3, including means for reducing the speed thereof; and Figures 6 and 7 are respectively front and side views of the speed reducing mechanism.

Like numerals of reference indicate like parts in all the views.

Referring particularly to the drawings, 3 and 6 denote preferably aligned driving shafts which constitute actuating means for my portable brush 1. I provide means for attaching the said parts 3 and 1 together so as to move in unison as by the plates 2, and the whole is supported when in operation by the handles 4 preferably located on opposite Specification of Letters Patent.

sides of the brush 1, which. latter may he readily removed for cleaning or removal purposes.

In the apparatus shown in Figures 1 and Patented May 2, 1922.

2, the driving shafts 3 and6 are operated by a motor 70 connected by wires 17 to a source of power, power being transmitted from the motor to the sald shaft 3 by the iexible shaft 6, preferably comprising coiled wire,

or by other suitable connecting means, the operation of the motor being governed by controlling means therefor as a switch 8. The respective and opposite. ends of the brush shaft and of the power shaft, as the fiexible shaft 6, are formed, as indicated by the dotted lines, with engaging devices having means whereby the said ends may be fastened together at will so as to cause the brush shaft to be rotated by the revolution of the Said power shaft.

I provide collars 5 in order to hold the handles 4 in position and from longitudinal movement, although' the same, being loose on the said shaft, are free to move'independently of the rot-ation of the latter. The shaft 3 is driven in this instance by the flexible shaft 6 and is preferably made independent of the shaft 3, the two said shafts having at their adjacent ends engaging or interlock,- ing means.

I sometimes construct my apparatus so that the motor shall form a part of the portable rotary brush as in Figure 3 where the shaft 3 is driven directly by the engaging means of the shaft of the motor 7 0 connected by wires 17 with a source of power, and having a controlling switch 18, the remainingvportions of the instrument being madethe class described comprises a box 10 containing the following mechanism:

A worm 16 on a supplemental shaft 90 which interlocks with the shaft 6 engages a gear 11 having pins 12 which enter slots in the periphery of the wheel 13, the shaft of p which Wheel carries a gear ill meshing with rthe handles i may be carried by either the shaft 3 or the motor casing. The saidshatt 3, and the shaft of the motor, and also the shafts 30 and 90 of the two-part connection of the gear case attachment 10 may all have engaging means at the adjacent ends thereof in order that the shafts 3 and 6 may be directly connected as shown in Figure 2; or else, if desired, the said two shafts may be engaged with the v intermediate connecting means comprising the motor shaft as illustrated in Figure 5; or the said shafts 3 and 6 may be engaged with the intermediate tWopart connection comprisingthe shafts 30 and 90 of the gear case 10 as shown in Figure 4; or the shaft 3 and the motor shaft may be engaged With the intermediate device commeier/ei.

prising the tWopart connection of the gear case l0, as illustrated 1n Figure 5.

l wish it to be understood that l do not desire to be limited to the particular use or Y -\longitudinally aligned means for operating said shaft and brush, and detachable means adapted to be placed intermediate said brush shaft and said operating means., whereby said brush shaft may be directly or indirectly connected to said operating means.

In testimony of the foregoing specification l do hereby sign the same in the city of New York, county and State of New York this 8th day of July, 1919.
